Culture's Calling: Mobile Phones, Gender, and the Making of an African Migrant Village in Lisbon

In this article, I explore how immigrants from the West African nation of Guinea-Bissau living in Portugal use mobile phones in their daily lives in Lisbon. Whereas one might assume that mobile phones and other new information technologies facilitate transnational communication between Africa and Portugal, the ethnographic fieldwork that I conducted in Lisbon from 1999 to 2003 revealed a different scenario. Instead, mobile phones as imagined and used by the Guinean immigrants I met in Lisbon revealed less about transnationalism and globalization than they did about constructing community and identity in a new locale. As Guinean immigrants in Portugal reconfigured their relationship to their former colonizers and struggled to make their way in a new, multicultural Europe, they used their mobile phones to engage local networks, shape local identities, and transform Lisbon's sprawl into an African migrant village. Here, I highlight the gendered dimensions of this process and contend that Guinean men's and women's varied uses of mobile phones in Lisbon underscore contrasting experiences of migration, mobility, and belonging.

Mycobacterium tuberculosis transmission in a country with low tuberculosis incidence: role of immigration and HIV infection

Immigrants from high-burden countries and HIV-coinfected individuals are risk groups for tuberculosis (TB) in countries with low TB incidence. Therefore, we studied their role in transmission of Mycobacterium tuberculosis in Switzerland. We included all TB patients from the Swiss HIV Cohort and a sample of patients from the national TB registry. We identified molecular clusters by spoligotyping and mycobacterial interspersed repetitive-unit-variable-number tandem-repeat (MIRU-VNTR) analysis and used weighted logistic regression adjusted for age and sex to identify risk factors for clustering, taking sampling proportions into account. In total, we analyzed 520 TB cases diagnosed between 2000 and 2008; 401 were foreign born, and 113 were HIV coinfected. The Euro-American M. tuberculosis lineage dominated throughout the study period (378 strains; 72.7%), with no evidence for another lineage, such as the Beijing genotype, emerging. We identified 35 molecular clusters with 90 patients, indicating recent transmission; 31 clusters involved foreign-born patients, and 15 involved HIV-infected patients. Birth origin was not associated with clustering (adjusted odds ratio [aOR], 1.58; 95% confidence interval [CI], 0.73 to 3.43; P = 0.25, comparing Swiss-born with foreign-born patients), but clustering was reduced in HIV-infected patients (aOR, 0.49; 95% CI, 0.26 to 0.93; P = 0.030). Cavitary disease, male sex, and younger age were all associated with molecular clustering. In conclusion, most TB patients in Switzerland were foreign born, but transmission of M. tuberculosis was not more common among immigrants and was reduced in HIV-infected patients followed up in the national HIV cohort study. Continued access to health services and clinical follow-up will be essential to control TB in this population.

The Blue Dog Coalition: Impact of a Single-Issue Caucus from the 104th to the 110th Congress

The Blue Dog Coalition is an informal organization of legislators within the House of Representatives that strives to influence policy on fiscal responsibility, attract the attention of the electorate, They are a group that elicits wide range of reactions covering the length of the political spectrum, but despite this, their claims of special defense of fiscal conservatism within the Democratic Party have gone relatively undocumented by the academic community.This project has integrated a party literature with a caucus literature, in the attempt of building a novel framework for research. Work on polarization, the significance of parties, the purpose and history of caucuses all have been fused in such away that the Blue Dogs have created an opportunity to test broad congressional questions on a caucus-microcosm scale. Three important questions have emerged from the many possible avenues of exploration on the topic: How does admission into the Blue Dog Coalition effect voting behavior - measured by interest, ideology, and party unityscores? How does party leadership delegate prestigious committee assignments, a traditional indicator of partisan favor and influence, towards Blue Dogs? Can we use the Blue Dog Coalition as an indicator of fiscal conservatism? To each of these questions, a number of interesting results emerged. Blue Dogs, in the 104th scored higher in conservative interest group scores, more towards the center in ideological methods, and lower in party unity Dogs began to behave closer to their Democratic counterparts. In addition, membership on these select committees rose from a very small number to greater proportional parity within the Democratic Party. Perhaps most interesting, the Blue Dog Coalition does behave as a significant, independent predictor effect on NTU scores, a variable used to demonstrate fiscal conservatism. This research has shown, first and foremost, that it is useful and practical to applyold arguments within the party literature to a smaller, caucus level of analysis that is relatively untouched by the political science field. For the Blue Dogs, specifically, we have tested the validity of their claims in an attempt to reach broader questions ofdemocratic responsibility and electoral clarity. This work, and other work I have drawn upon, has barely scratched the surface on Blue Dog Democrats and other caucuses of comparable influence and popularity, and there remains a wealth of research material onthis caucus alone to be explored by scholars in the field of congressional politics.

An anatomical investigation of the cervicothoracic ganglion

Anatomical variability within the autonomic nervous system has long been accepted. This study evaluated the anatomical variability of the cervicothoracic ganglion (CTG) according to its form and, in addition, provided precise measurements between the CTG and the anterior tubercle of the transverse process of the sixth cervical vertebra (C6TP), the first costovertebral articulation, and the vertebral artery. Forty-two adult cadavers were dissected, 22 male and 20 females. Five main forms of CTG were documented; spindle (31.9%), dumbbell (23.2%), truncated (21.7%), perforated (14.5%), and inverted-L (8.7%). The means for length, width, and thickness of the CTG were 18.5 mm, 8.2 mm, and 4.5 mm, respectively. The dimensions were found to be slightly larger in the males than females and on the left sides as compared to the right. The mean shortest distance between the CTGs and the vertebral artery was found to be 2.8 mm, whilst the mean shortest distances to C6TP was 25.7 mm and to the first costovertebral articulation was 1.7 mm. There is great variability in the morphology of the CTG with five common forms consistently seen. The relation to the vertebral artery may influence the form of the ganglion. Two previously undocumented forms are recorded; the truncated which describes the important juxtaposition of the CTG and the vertebral artery and the perforated which describes the piercing of the ganglion itself by the artery. The findings are considered to be of clinical importance to anesthetists, surgeons, neurosurgeons, and anatomists.

Characterization of Aggregatibacter actinomycetemcomitans strains in periodontitis patients in Germany

Aggregatibacter actinomycetemcomitans strains of serotype b and with a deletion of 530 bp in the promoter region of the leukotoxin gene (JP2 clone) are known to be associated with severe periodontitis. Our study was aimed to detect virulence genes of A. actinomycetemcomitans strains obtained from patients living in four German cities with different proportions of immigrants.

Passage of Alabama's Hb 56: Fueled By Dominant Anti-Immigration Tropes

Abstract Background. In 2011, Alabama, neither a border state nor hold a significantly large Hispanic population, passed the most restrictive state immigration law, The Beason-Hammon Alabama Taxpayer and Citizen Protection Act, HB 56. This omnibus law was far-reaching in its restrictions, including, but not limited to, identification, public services, employment, housing, and law enforcement. Objectives. This research explores the dominant tropes present in the narrative surrounding the anti-immigration legislative activity in Alabama that created fertile ground for the passage of such a punitive immigration law. Methods. Newspaper articles from 2007 to 2011 in Alabama¿s Birmingham News and Press-Register, the two most circulated newspapers in the state, were attained from NewsLibrary.com, an online database of 5,311 newspapers and other news sources. Results. Seven dominant tropes were identified in the articles that pushed for anti-immigration policies. These tropes claimed (1) the US-Mexico border is not secure, (2) the federal government has failed to enact comprehensive immigration reform, (3) immigrants steal jobs, hurt the economy, and (4) burden public services, (5) immigrants are criminals and terrorists, (6) they refuse to assimilate and learn English, and (7) there has been a dramatic percent change in the Hispanic and illegal populations. These tropes cumulatively worked together to create anti-immigration sentiment that pushed for the passage of HB 56.

Gender distribution of suicide attempts among immigrant groups in European countries--an international perspective

Studies report high rates of suicide attempts for female immigrants. This study assesses variations in the distribution of suicide attempts across gender in immigrant and non-immigrant groups in Europe.

The Role of Parasitism in Adaptive Radiations - When Might Parasites Promote and When Might They Constrain Ecological Speciation?

Research on speciation and adaptive radiation has flourished during the past decades, yet factors underlying initiation of reproductive isolation often remain unknown. Parasites represent important selective agents and have received renewed attention in speciation research. We review the literature on parasite-mediated divergent selection in context of ecological speciation and present empirical evidence for three nonexclusive mechanisms by which parasites might facilitate speciation: reduced viability or fecundity of immigrants and hybrids, assortative mating as a pleiotropic by-product of host adaptation, and ecologically-based sexual selection. We emphasise the lack of research on speciation continuums, which is why no study has yet made a convincing case for parasite driven divergent evolution to initiate the emergence of reproductive isolation. We also point interest towards selection imposed by single vs. multiple parasite species, conceptually linking this to strength and multifariousness of selection. Moreover, we discuss how parasites, by manipulating behaviour or impairing sensory abilities of hosts, may change the form of selection that underlies speciation. We conclude that future studies should consider host populations at variable stages of the speciation process, and explore recurrent patterns of parasitism and resistance that could pinpoint the role of parasites in imposing the divergent selection that initiates ecological speciation.

Leiomyomatoid angiomatous neuroendocrine tumor (LANT) of the pituitary: a distinctive biphasic neoplasm with primitive secretory phenotype and smooth muscle-rich stroma

We describe a hitherto undocumented variant of dimorphic pituitary neoplasm composed of an admixture of neurosecretory cells and profuse leiomyomatous stroma around intratumoral vessels. Radiologically perceived as a macroadenoma of 3.8 cm in diameter, this pituitary mass developed in an otherwise healthy 43-year-old female. At the term of a yearlong history of amenorrhea and progressive bitemporal visual loss, subtotal resection was performed via transsphenoidal microsurgery. Discounting mild hyperprolactinemia, there was no evidence of excess hormone production. Histologically, solid sheets, nests and cords of epithelial-looking, yet cytokeratin-negative cells were seen growing in a richly vascularized stroma of spindle cells. While strong immunoreactivity for NCAM, Synaptophysin and Chromogranin-A was detected in the former, the latter showed both morphological and immunophenotypic hallmarks of smooth muscle, being positive for vimentin, muscle actin and smooth muscle actin. Architectural patterns varied from monomorphous stroma-dominant zones through biphasic neuroendocrine-leiomyomatous areas, to pseudopapillary fronds along vascular cores. Only endothelia were labeled with CD34. Staining for S100 protein and GFAP, characteristics of sustentacular cells, as well as bcl-2 and c-kit was absent. Except for alpha-subunit, anterior pituitary hormones tested negative in tumor cells, as did a panel of peripheral endocrine markers, including serotonin, somatostatin, calcitonin, parathormone and vasoactive intestinal polypeptide. Mitotic activity was absent and the MIB-1 labeling index low (1-2%). While assignment of this lesion to any established neoplastic entity is not forthcoming, we propose it is being considered as a low-grade neuroendocrine tumor possibly related to null cell adenoma.

Asia Comes to Main Street and May Learn to Speak Spanish: Globalization in a Poor Neighborhood in Worcester

This paper considers how and why an Asian enclave of small businesses has appeared in a poor neighborhood characterized by Puerto Rican and other Latino immigration in the post-industrial city of Worcester, Massachusetts. We begin by examining the role of the US in the world system, and argue that the US hegemonic role and specific political economic aspects of global capitalism (ie. deindustrialization) account for some of the migration stream. Next, using socioeconomic and historical data, interviews, and observations, we outline the history of Worcester’s economy and immigration patterns. We demonstrate that the increasing economic inequality leaves few promising employment options for newcomers to Worcester. Drawing on existing literature on immigrant entrepreneurs and ethnic enclaves, we argue that some aspects of the literature appear to shed light on the Vietnamese enterprises which have so visibly appeared (e.g., ethnic niches), while others, (e.g., middle-man minority theory) are not now reflected in local conflict. We conclude by considering the prospects for immigrants to this neighborhood in light of its political economic context.

A common ancestral glycoprotein (GP) 9 1828A>G (Asn45Ser) gene mutation occurring in European families from Australia and Northern Europe with Bernard-Soulier Syndrome (BSS)

Bernard-Soulier syndrome (BSS) is an extremely rare hereditary bleeding disorder, caused by mutations occurring in the Glycoprotein (GP) Ibalpha, GPIbbeta and GP9 genes that encode for the corresponding subunits of platelet GPIb-V-IX adhesion receptor complex. BSS has been reported in many populations, mostly behaving in an autosomal-recessive manner.While the great majority of BSS mutations are unique to a single individual or family, the GP9 1828A>G Asn45Ser mutation, which we have identified in an undocumented Australian Caucasian, has already been reported in multiple unrelated Caucasian families from various Northern and Central European countries. Haplotype analysis of 19 BSS patients from 15 unrelated Northern European families (including 2 compound heterozygote siblings from a British family previously published, and 17 1828A>G Asn45Ser homozygotes), showed that 14 of these BSS patients from 11 of the 1828A>G Asn45Ser homozygote families share a common haplotype at the chromosomal region 3' to the GP9 gene. Hence, the results suggest that the GP9 1828A>GAsn45Ser mutation in these families is ancient, and its frequent emergence in the European population is the result of a founder effect rather than recurrent mutational events. Association of the 1828A>G Asn45Ser mutation with variant haplotypes in 4 other Northern European BSS families raised the possibility of a second founder event, or rare recombinations in these families. Additional members from these 'atypical' lineages would need to be screened to resolve this question.

Asthma in young south Asian women living in the United Kingdom: the importance of early life

BACKGROUND: Studies of immigrants suggest that the environment during fetal life and duration of residence in the host country might influence the development of asthma. Little is known about the importance of the timing of the exposure in the host country and whether migrants might be especially vulnerable in certain age windows. OBJECTIVE: We compared the reported prevalence of asthma between young white and south Asian women in the United Kingdom, and investigated associations with country of birth and age at immigration. METHODS: A questionnaire on atopic disorders was posted to 2380 south Asian and 5796 white young mothers randomly sampled in Leicestershire. Data on ethnicity were also available from maternity records. Data were analysed using multivariable logistic regression and a propensity score approach. Results The reported prevalence of asthma was 10.9% in south Asian and 21.8% in white women. South Asian women who migrated to the United Kingdom aged 5 years or older reported less asthma (6.5%) than those born in the United Kingdom or who migrated before age 5 (16.0%), with an adjusted odds ratio of 0.38 [95% Confidence Interval 0.23-0.64, P<0.001]. For those who migrated aged over 5 years, the prevalence did not alter with the duration of residence in the United Kingdom. Current exposure to common environmental risk factors had relatively little effect on prevalence estimates. CONCLUSION: These data from a large population-based study support the hypothesis that early life environmental factors influence the risk of adult asthma.

Fine-scale genetic structure and dispersal in the common vole (Microtus arvalis)

The genetic structure and demography of local populations is tightly linked to the rate and scale of dispersal. Dispersal parameters are notoriously difficult to determine in the field, and remain often completely unknown for smaller organisms. In this study, we investigate spatial and temporal genetic structure in relation to dispersal patterns among local populations of the probably most abundant European mammals, the common vole (Microtus arvalis). Voles were studied in six natural populations at distances of 0.4-2.5 km in three different seasons (fall, spring, summer) corresponding to different life-history stages. Field observations provided no direct evidence for movements of individuals between populations. The analysis of 10 microsatellite markers revealed a persistent overall genetic structure among populations of 2.9%, 2.5% and 3% FST in the respective season. Pairwise comparisons showed that even the closest populations were significantly differentiated from each other in each season, but there was no evidence for temporal differentiation within populations or isolation by distance among populations. Despite significant genetic structure, assignment analyses identified a relatively high proportion of individuals as being immigrants for the population where they were captured. The immigration rate was not significantly lower for females than for males. We suggest that a generally low and sex-dependent effective dispersal rate as the consequence of only few immigrants reproducing successfully in the new populations together with the social structure within populations may explain the maintenance of genetic differentiation among populations despite migration.

Finnish Miners versus Ivy League Capitalists

Finnish immigrants were recruited to work in the copper mines of Michigan by Boston capitalists intimately associated with Harvard. Boston capitalists defined the culture of capitalism in the United States. They extended their culture across the continent as they acquired mines and railroads. Finnish workers encountered Ivy League capitalism in Michigan, Minnesota, Idaho, Montana, Wyoming, Colorado, Utah and Arizona—often with the same interrelated group of capitalists. The two groups continually met in explosive confrontations in Montana, Michigan, Minnesota, and Arizona. To the Ivy League capitalists, Finns were terrorists who threatened the American social order. For the Finns, it was a war for social justice. In my presentation, I will trace the experience of Finnish workers in corporations controlled by Ivy League capitalists from the first strike at Calumet & Hecla in 1873 to the Red Scare of 1919-1921.
